Chemotactic response of neutrophils to serum treated with (a) Bjussu and (b) Bpir crude venom. Normal human serum (NHS) was treated with crude venom, zymosan (positive control), or TEA-Ca²⁺-Mg²⁺ buffer (negative control). Crude venoms were also incubated with TEA-Ca²⁺-Mg²⁺buffer alone or heat-inactivated NHS. Data are expressed as the mean ± standard deviation of three independent experiments assayed in duplicate. *p < 0.05 or ***p < 0.0001 vs. negative control. Bjussu: Bothrops jararacussu; Bpir: Bothrops pirajai
